We characterize the superionic phase transition and the lattice and electronic structures of the archetypal type-I superionic conductor alpha-AgI using extensive first-principles molecular dynamics calculations. We find that superionicity is signaled by a ...
A novel adsorber with a structured fixed-bed made of sintered metal fibres (SMF) plates has been developed for purification of low-content VOCs gas-streams. The surface of the metal fibres was coated by a thin, homogeneous MFI-type (ZSM-5, Silicalite-1) ze ...
Many manufacturers have started to use virtual stores as a direct distribution channel in addition to their existing indirect retail channels. These companies must now decide how to integrate these channels. The alternatives are to operate dedicated distri ...
This paper presents a novel algorithm for robust object recognition. We propose to model the visual appearance of objects via probability density functions. The algorithm consists of a fully connected Markov random field with energy function derived from r ...
Snow avalanches are rapid, gravity-driven, mass flows involving snow, air, and sometimes debris (logs, stones, etc.). Two idealized types of avalanches are usually considered when one is interested in describing their motion. ...
The kink instability of a magnetized plasma column (flux rope) is a fundamental process observed in laboratory and in natural plasmas. Previous theoretical, experimental, and observational work has focused either on the case of periodic (infinite) ropes (r ...
Trust and reputation systems have proven to be essential to enforcing cooperative behavior in peer-to-peer networks. We briefly describe the current approaches to building reputation systems: social networks formation, probabilistic estimation and game the ...
This paper presents a novel locomotion concept for mobile micro robots: the “friction drive principle”. It allows for easy miniaturization and high velocities for low power consumption and simple onboard electronics. A prototype (Ø20 mm × 7.5 mm) with two ...
We characterize and improve an existing infrared relative localization/communication module used to find range and bearing between robots in small-scale multi-robot systems. Modifications to the algorithms of the original system are suggested which offer b ...
A new scanner design for a high-speed atomic force microscope (AFM) is presented and discussed in terms of modeling and control. The lowest resonance frequency of this scanner is above 22 kHz. The X and Y scan ranges are 13 micrometers and the Z range is 4 ...
